Depends on what YOU value more... or what you'd miss the most if it wasn't there.
DME from the airport
EMH at the parks
Package delivery to your resort
Availability of the DDP
Themed resort (even if the theme is somewhat subtle at OKW)
Little "Disney" reminders around the resort
Then take the OKW studio and you'll be very happy you did.
Larger, more comfortable and luxurious room
Better pools
Walk to several upscale restaurants
Walk to full-service spa (adjacent hotels, much closer than OKW-to-SSR)
Possibly a high rise view of fireworks from your room
Then take the Wyn BC 1BR and you'll be very happy you did.
The OKW studios used to have two queen beds but no sofa for sitting together, even if just for unwinding with a drink or watching a little TV together. Even though you don't have children/others traveling with you, if either of you snores or if either of you likes to be up alone, very early (like my DH) or very late, having a separate room is appreciated. If these things don't apply to your situation, then they may not affect your decision.
FWIW, our DD is also acquainted with DVC and WBC resorts. For a week of her honeymoon, DD and DSIL were offered an RCI exchange week as a gift. Their 1st choice was AKV 1BR, 2nd choice was WBC 1BR, 3rd was any DVC 1BR and last was AKV studio. No other onsite DVC studio would have pleased them for their honeymoon and they would have chosen an oceanfront week instead. They spent a lovely week in a 1BR at AKV Kidani. They used their kitchen for breakfasts and after-dinner blender drinks. They loved having a true master suite with a private, inroom jacuzzi, rather than a queen bed in a single room with a microwave/mini-fridge on the wall.
We've stayed at both OKW and WBC, in those unit sizes. We find the ambiance at both resorts, though different, to be similarly appealing, relaxing and romantic, especially at night. As free standing resorts, with all their resort amenities and comparing
1BRs at both, I much prefer WBC. However, when we specifically want the Disney benefits (listed above) for a particular trip, especially for a commando-style parks trip, I do prefer a DVC or deluxe onsite resort and OKW is a very lovely onsite resort. And while I've become spoiled by larger units, I would consider a studio if I want those onsite perks enough.
So, again, consider what YOU would find most bothersome to miss, from each perspective, and choose. You won't regret that. Once you make your decision, don't second-guess yourself. Just enjoy the planning around where you will be. You
really won't go wrong with either one - they're both great resorts!
HTH!
